Quote context

[...]

- Your voice shall be as strong as any man's in the disposing of new dignities.

- Only be patient till we have appeased the multitude beside themselves with fear.

- And then we will deliver you the cause why I, that did love Caesar when I struck him, have thus proceeded.

- I doubt not of your wisdom.

- Let each man render me his bloody hand.

- First, Marcus Brutus, do I shake with you.

- Next, Caius Cassius, do I take your hand. Now, Decius Brutus, yours. Yours, Metellus. Yours, Cinna. And my valiant Casca, yours.

- Though last, not least in love, yours, good Trebonius.

- Gentlemen all.

- Alas, what shall I say? My credit now stands on such slippery ground, that one of two bad ways you must conceit me, either a coward or a flatterer.
